` Specification of Letters Patent.

Patented Feb. 25, 1908.

f Application filed July 30.1907. Serial No. 386.286.

To all whom it may concern.'

Be it known that I, BERTRAND E. BEYER, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Shutter-B owers;and I do hereby declare the following to be a full, clear, and exactdescriptionof the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to figures of reference markedthereon, which form a part of this specification.

This invention relates to an adjusting device to be attached to blinds,shutters, doors and similar structures, and is designed to hold theswinging member, for instance a shutter, at any 'point in its radius ofmovement, and to securely lock it in the position in which it has beenadjusted.

The invention provides an article of this kind embodying a slide-piecethat is adapted to lock the shutter, the slide-piece having ngers whichprovide for its manipulation, whereby the shutter is opened by means ofthe adjuster, and one hand can be used for the whole operation, thishandle providing also for releasing the locking means when it is graspedfor its mani ulation. In this way the releasing and the ocking arecoincident with the respective grasping and letting go of thefinger-piece by the person operating the device.

The invention is illustrated in the accompanying drawing, in whichFigure 1 is a perspective view of the device mounted on a window casingand shutter. Fig. 2 is a section of the slide-piece and lockingmechanism. Fig. 3 is a section of the window frame, but showing theshutter and the adjusting mechanism in elevation, and illustrating theshutter in its open position by a dotted outline.-

I secure to the window casing or frame 10, the standard 11, securing itpreferably by means of the screws 12, and on this standard is pivoted anarm 13 which swings when the shutter is opened or closed, the other endof the arm 13 being pivoted between the ears 14 of the slide-piece 15.The slide-piece is hollow and has perforations 16 through which passesthe rod 17. The rod 17 is secured, on its two ends by means of theplates 1S and the screws 19, to the shutter 20.

This vstructure allows the slide-piece to travel along the rod 17, andthe shutter can be swung open to its full extent, as shown in Fig. 3, inwhich position the slide-piece 15 is on the end-of the rod nearest thehinge 21. One wall of the slide-piece 15 has the perforations 22 throughwhich project the iinger-pieces 23, the inner ends 24 of theiingerpieces being perforated, the perforations allowing the passage ofthe rod 17. The finger pieces are thus fulcrumed, intermediate of theirends, in the perforations 22, and are normally pushed toward one anotherby means of the springs 25. The inner ends 24 of the finger-pieces arethus inclined at an angle to the rod 17, and are thereby made to bitethe rod 17 at any point where -the iinger-pieces are released.

When the iinger-pieces 23 are grasped between the thumb and forefingerof the operators hand, the inner ends 24 of the iingerpieces are forcedagainst the action of the springs. 25, and the. perforations in the ends24 are 1n line, or approximately so, and they thus offer no resistanceto the slide-piece traveling on the rod 17, and by sliding theslide-piece, by means of the finger-pieces along the rod, the shutter isoperated, and when there are two shutters to a window they can be openedsimultaneously, one hand being used on the iinger-pieces of eachshutter. Whenever the shutter is in the position it is desired to haveit, the operator simply releases the iinger-pieces, the springs 25 forcethe inner ends of the iinger-pieces so that they bind on the rod, andthe shutter is held against any movement. The standard 11 is so disposedthat the arm 13 will not interfere with the hinge of the shutter, whenthe shutter is thrown open as indicated in the dotted outline in Fig. 3.

If desired, I can replace the two compression springs 25, shown in Fig.'2, by any other usual style of spring that will bring about the bindingof the ends 24 of the fingerieces on the rod 17.

T e articular shapes and outline of the respectlve parts of thisinvention can be altered to suit the style of house or building on whichit is to be used.

Having thus described my invention, what I claim is:q

In combination with a casing having a swinging member, of a standardsecured to the casing, an arm having one end secured to the standard andarranged to L swing inner ends of the finger-pieces in engage- 1thereon, a sliding member pivotally secured ment with the rod to lockthe same.
